Early Models of Evolution Millions of species of plants animals and other organisms

live on Earth today Do you suppose they are exactly the same asthey were when they first appearedmdashor have any of themchanged A species is a group of organisms that share similarcharacteristics and can reproduce among themselves to producefertile offspring Many characteristics of a species are inheritedwhen they pass from parent to offspring Change in these inher-ited characteristics over time is evolution Figure 1 shows howthe characteristics of the camel have changed over time

Describe Lamarckrsquos hypothesis of acquired characteristics and Darwinrsquos theory of natural selection

SECTION 1 Ideas About Evolution 155

Hypothesis of Acquired Characteristics In 1809 JeanBaptiste de Lamarck proposed a hypothesis to explain howspecies change over time He suggested that characteristics ortraits developed during a parent organismrsquos lifetime are inher-ited by its offspring His hypothesis is called the inheritance ofacquired characteristics Scientists collected data on traits thatare passed from parents to offspring The data showed that traitsdeveloped during a parentrsquos lifetime such as large muscles builtby hard work or exercise are not passed on to offspring The evi-dence did not support Lamarckrsquos hypothesis

What was Lamarckrsquos explanation of evolution

Darwinrsquos Model of EvolutionIn December 1831 the HMS Beagle sailed from England on

a journey to explore the South American coast On board was ayoung naturalist named Charles Darwin During the journeyDarwin recorded observations about the plants and animals hesaw He was amazed by the variety of life on the GalaacutepagosIslands which are about 1000 km from the coast of EcuadorDarwin hypothesized that the plants and animals on theGalaacutepagos Islands originally must have come from Central andSouth America But the islands were home to many species hehad not seen in South America including giant cactus treeshuge land tortoises and the iguana shown in Figure 2

Figure 2 This map shows theroute of Darwinrsquos voyage on the HMS Beagle Darwin noticed manyspecies on the Galaacutepagos Islandsthat he had not seen along thecoast of South America includingthe marine iguana This species isthe only lizard in the world knownto enter the ocean and feed onseaweed

Darwinrsquos Observations Darwin observed 13 species offinches on the Galaacutepagos Islands He noticed that all 13 specieswere similar except for differences in body size beak shape andeating habits as shown in Figure 3 He also noticed that all theGalaacutepagos finch species were similar to one finch species he hadseen on the South American coast

Darwin reasoned that the Galaacutepagos finches must have hadto compete for food Finches with beak shapes that allowedthem to eat available food survived longer and produced moreoffspring than finches without those beak shapes After manygenerations these groups of finches became separate species

How did Darwin explain the evolution of the dif-ferent species of Galaacutepagos finches

Natural SelectionAfter the voyage Charles Darwin returned to England and

continued to think about his observations He collected moreevidence on inherited traits by breeding racing pigeons He alsostudied breeds of dogs and varieties of flowers In the mid 1800sDarwin developed a theory of evolution that is accepted by mostscientists today He described his ideas in a book called On theOrigin of Species which was published in 1859

Figure 3 Darwin observed that the beak shape of eachspecies of Galaacutepagos finch is related to its eating habits

Finches with medium-sized beakseat a variety of foods includingseeds and insects

Finches that feed on insects havelong slender beaks for probingbeneath tree bark

Finches that eat nuts and seedshave short strong beaks for breaking hard shells

Darwinrsquos Theory Darwinrsquos observations led manyother scientists to conduct experiments on inheritedcharacteristics After many years Darwinrsquos ideas becameknown as the theory of evolution by natural selectionNatural selection means that organisms with traits bestsuited to their environment are more likely to surviveand reproduce Their traits are passed to more offspringAll living organisms produce more offspring than sur-vive Galaacutepagos finches lay several eggs every few monthsDarwin realized that in just a few years several pairs offinches could produce a large population A population isall of the individuals of a species living in the same areaMembers of a large population compete for living spacefood and other resources Those that are best able to sur-vive are more likely to reproduce and pass on their traitsto the next generation

The principles that describe how natural selectionworks are listed in Table 1 Over time as new data wasgathered and reported changes were made to Darwinrsquosoriginal ideas about evolution by natural selection Histheory remains one of the most important ideas in thestudy of life science

1 Organisms produce more offspring than can survive

2 Differences or variations occur among individuals of a species

3 Some variations are passed to offspring

4 Some variations are helpful Individuals with helpful variations survive and reproduce better than those without these variations

5 Over time the offspring of individuals with helpful variations make up more of a population and eventually may become a separate species

Variation and AdaptationDarwinrsquos theory of evolution by natural selection empha-

sizes the differences among individuals of a species These dif-ferences are called variations A variation is an inherited traitthat makes an individual different from other members of itsspecies Variations result from permanent changes or muta-tions in an organismrsquos genes Some gene changes produce smallvariations such as differences in the shape of human hairlinesOther gene changes produce large variations such as an albinosquirrel in a population of gray squirrels or fruit without seedsOver time more and more individuals of the species mightinherit these variations If individuals with these variations con-tinue to survive and reproduce over many generations a newspecies can evolve It might take hundreds thousands or mil-lions of generations for a new species to evolve

Some variations are more helpful than others An adaptationis any variation that makes an organism better suited to its envi-ronment The variations that result in an adaptation can involvean organismrsquos color shape behavior or chemical makeupCamouflage (KA muh flahj) is an adaptation A camouflagedorganism like the one shown in Figure 4 blends into its envi-ronment and is more likely to survive and reproduceFigure 4 Variations that

provide an advantage tend toincrease in a population overtime Variations that result ina disadvantage tend todecrease in a population over time

Albinism can prevent an organism from blending into its environmentInfer what might happen to an albino lemur in its natural environment

Camouflage allows organisms to blend into their environments Infer how its coloration gives this scorpion fish a survival advantage

Changes in the Sources of Genes Over time the geneticmakeup of a species might change its appearance For exampleas the genetic makeup of a species of seed-eating Galaacutepagosfinch changed so did the size and shape of its beak Many kindsof environmental factors help bring about changes When indi-viduals of the same species move into or out of an area theymight bring in or remove genes and variations Suppose a fam-ily from another country moves to your neighborhood Theymight bring different foods customs and ways of speaking withthem In a similar way when new individuals enter an existingpopulation they can bring in different genes and variations

Geographic Isolation Sometimes mountains lakes orother geologic features isolate a small number of individualsfrom the rest of a population Over several generations varia-tions that do not exist in the larger population might begin to bemore common in the isolated population Also gene mutationscan occur that add variations to populations Over time the twopopulations can become so different that they no longer canbreed with each other The two populations of rabbits shown inFigure 5 have been geographically isolated from each other forthousands of generations

Figure 5 About 600 years ago European rab-bits were introduced to the Canary Islands froma visiting Portuguese ship The Canary Islandsare in the Atlantic Ocean off the northwest coastof Africa Over time the Canary Island rabbitsbecame a separate species

Canary Island rabbits feed during the night Explain why large eyes might be considered a helpful adaptation in Canary Island rabbits

European rabbits like the one above feedduring the day and are fairly large

The Speed of EvolutionScientists do not agree on how quickly evolution occurs

Many scientists hypothesize that evolution occurs slowly per-haps over tens or hundreds of millions of years Other scientistshypothesize that evolution can occur quickly Most scientistsagree that evidence supports both of these models

Gradualism Darwin hypothesized that evolution takes placeslowly The model that describes evolution as a slow ongoingprocess by which one species changes to a new species is knownas gradualism According to the gradualism model a continu-ing series of mutations and variations over time will result in anew species Look back at Figure 1 which shows the evolutionof the camel over tens of millions of years Fossil evidence showsa series of intermediate forms that indicate a gradual changefrom the earliest camel species to todayrsquos species

Punctuated Equilibrium Gradualism doesnrsquot explain theevolution of all species For some species the fossil record showsfew intermediate formsmdashone species suddenly changes toanother According to the punctuated equilibrium model rapidevolution comes about when the mutation of a few genes resultsin the appearance of a new species over a relatively short periodof time The fossil record gives examples of this type of evolu-tion as you can see in Figure 6

Figure 6 The hypothesized evo-lution of bears illustrates the punc-tuated equilibrium model ofevolution Discuss how the six species on thefar right are explained better bypunctuated equlibrium

SummaryEarly Models of Evolution

bull Evolution is change in the characteristics of aspecies over time

bull Lamarck proposed the hypothesis of inheritedacquired characteristics

Natural Selection

bull Darwin proposed evolution by natural selec-tion a process by which organisms bestsuited to their environments are most likely tosurvive and reproduce

bull Organisms have more offspring than can sur-vive individuals of a species vary and manyof these variations are passed to offspring

Variation and Adaptation

bull Adaptations are variations that help an organ-ism survive or reproduce in its environment

bull Mutations are the source of new variations

The Speed of Evolution

bull Evolution may be a slow or fast processdepending on the species under study

7 Use Percentages The evolution of the camel can betraced back at least 56 million years Use Figure 1 toestimate the percent of this time that the moderncamel has existed

Punctuated Equilibrium Today Evolution by the punctu-ated equilibrium model can occur over a few thousand or mil-lion years and sometimes even faster For example manybacteria have changed in a few decades The antibiotic penicillinoriginally came from the fungus shown in Figure 7 But manybacteria species that were once easily killed by penicillin nolonger are harmed by it These bacteria have developedresistance to the drug Penicillin has been in use since1943 Just four years later in 1947 a species of bacteriathat causes pneumonia and other infections already haddeveloped resistance to the drug By the 1990s several dis-ease-producing bacteria had become resistant to peni-cillin and many other antibiotics

How did penicillin-resistant bacteria evolve soquickly As in any population some organisms have vari-ations that allow them to survive unfavorable living con-ditions when other organisms cannot When penicillinwas used to kill bacteria those with the penicillin-resist-ant variation survived reproduced and passed this trait totheir offspring Over a period of time this bacteria popu-lation became penicillin-resistant

Types of FossilsMost of the evidence for evolution comesfrom fossils A fossil is the remains an

imprint or a trace of a prehistoric organism Several types of fos-sils are shown in Figure 9 Most fossils are found in sedimentaryrock Sedimentary rock is formed when layers of sand silt clayor mud are compacted and cemented together or when mineralsare deposited from a solution Limestone sandstone and shaleare all examples of sedimentary rock Fossils are found moreoften in limestone than in any other kind of sedimentary rockThe fossil record provides evidence that living things haveevolved

Determining a Fossilrsquos AgePaleontologists use detective skills to determine the age of

dinosaur fossils or the remains of other ancient organisms Theycan use clues provided by unique rock layers and the fossils theycontain The clues provide information about the geologyweather and life-forms that must have been present during eachgeologic time period Two basic methodsmdashrelative dating andradiometric datingmdashcan be used alone or together to estimatethe ages of rocks and fossils

Relative Dating One way to find the approximate age of fos-sils found within a rock layer is relative dating Relative dating isbased on the idea that in undisturbed areas younger rock layersare deposited on top of older rock layers as shown in Figure 10 Relative dating provides only an estimate of a fossilrsquosage The estimate is made by comparing the ages of rock layersfound above and below the fossil layer For example suppose a 50-million-year-old rock layer lies below a fossil and a 35-million-year-old layer lies above it According to relative datingthe fossil is between 35 million and 50 million years old

Why can relative dating be used onlyto estimate the age of a fossil

Radiometric Dating Scientists can obtain a more accurateestimate of the age of a rock layer by using radioactive elementsA radioactive element gives off a steady amount of radi-ation as it slowly changes to a nonradioactive elementEach radioactive element gives off radiation at a differentrate Scientists can estimate the age of the rock by com-paring the amount of radioactive element with theamount of nonradioactive element in the rock Thismethod of dating does not always produce exact resultsbecause the original amount of radioactive element inthe rock can never be determined for certain

Fossils and EvolutionFossils provide a record of organisms that lived in the past

However the fossil record is incomplete or has gaps much likea book with missing pages The gaps exist because most organ-isms do not become fossils By looking at fossils scientists con-clude that many simpler forms of life existed earlier in Earthrsquoshistory and more complex forms of life appeared later as shownin Figure 11 Fossils provide indirect evidence that evolution hasoccurred on Earth

Almost every week fossil discoveries are made somewhere inthe world When fossils are found they are used to help scien-tists understand the past Scientists can use fossils to make mod-els that show what the organisms might have looked like Fromfossils scientists can sometimes determine whether the organ-isms lived in family groups or alone what types of food they atewhat kind of environment they lived in and many other thingsabout them Most fossils represent extinct organisms From astudy of the fossil record scientists have concluded that morethan 99 percent of all organisms that have ever existed on Earthare now extinct

More Clues About EvolutionBesides fossils what other clues do humans have about evo-

lution Sometimes evolution can be observed directly Plantbreeders observe evolution when they use cross-breeding toproduce genetic changes in plants The development of antibi-otic resistance in bacteria is another direct observation of evolu-tion Entomologists have noted similar rapid evolution ofpesticide-resistant insect species These observations providedirect evidence that evolution occurs Also many examples ofindirect evidence for evolution exist They include similarities inembryo structures the chemical makeup of organisms includ-ing DNA and the way organisms develop into adults Indirectevidence does not provide proof of evolution but it does sup-port the idea that evolution takes place over time

Embryology The study of embryos and their development iscalled embryology (em bree AH luh jee) An embryo is the ear-liest growth stage of an organism A tail and pharyngeal pouchesare found at some point in the embryos of fish reptiles birdsand mammals as Figure 12 shows Fish develop gills but theother organisms develop other structures as their developmentcontinues Fish birds and reptiles keep their tails but manymammals lose theirs These similarities suggest an evolutionaryrelationship among all vertebrate species

Homologous Structures What do the structures shown inFigure 13 have in common Although they have different func-tions each of these structures is made up of the same kind ofbones Body parts that are similar in origin and structure arecalled homologous (hoh MAH luh gus) Homologous struc-tures also can be similar in function They often indicate thattwo or more species share common ancestors

What do homologous structures indicate

Vestigial Structures The bodies of some organisms include vestigial (veh STIH jee ul) structuresmdashstructures thatdonrsquot seem to have a function Vestigial structures also provideevidence for evolution For example manatees snakes andwhales no longer have back legs but like all animals with legsthey still have pelvic bones The human appendix is a vestigialstructure The appendix appears to be a small version of thececum which is an important part of the digestive tract of manymammals Scientists hypothesize that vestigial structures likethose shown in Figure 14 are body parts that once functionedin an ancestor

Figure 14 Humans have three smallmuscles around each ear that are vestigialIn some mammals such as horses these muscles are large They allow a horse to turn its ears toward the source of a sound Humans cannot rotate their ears but some people can wiggle their ears

Figure 13 A porpoise flipperfrog forelimb human arm and batwing are homologous These struc-tures show different arrangementsand shapes of the bones of theforelimb They have the samenumber of bones muscles andblood vessels and they developedfrom similar tissues

DNA If you enjoy science fiction you prob-ably have read books or seen movies in whichscientists re-create dinosaurs and otherextinct organisms from DNA taken from fos-sils DNA is the molecule that controls hered-ity and directs the development of everyorganism In a cell with a nucleus DNA isfound in genes that make up the chromo-somes Scientists compare DNA from living organisms to iden-tify similarities among species Examinations of ancient DNAoften provide additional evidence of how some species evolvedfrom their extinct ancestors By looking at DNA scientists alsocan determine how closely related organisms are For exampleDNA studies indicate that dogs are the closest relatives of bears

Similar DNA also can suggest common ancestry Apes suchas the gorillas shown in Figure 15 chimpanzees and orangutanshave 24 pairs of chromosomes Humans have 23 pairs Whentwo of an apersquos chromosomes are laid end to end a match forhuman chromosome number 2 is formed Also similar proteinssuch as hemoglobinmdashthe oxygen-carrying protein in red bloodcellsmdashare found in many primates This can be further evidencethat primates have a common ancestor

Primates Humans monkeys and apes belong to the group of mam-

mals known as the primates All primates have opposablethumbs binocular vision and flexible shoulders that allow thearms to rotate These shared characteristics indicate that all pri-mates may have evolved from a common ancestor

Having an opposable thumb allows you to cross your thumbover your palm and touch your fingers This means that you cangrasp and hold things with your hands An opposable thumballows tree-dwelling primates to hold on to branches

Binocular vision permits you to judge depth or distance withyour eyes In a similar way it allows tree-dwelling primates tojudge the distances as they move between branches Flexibleshoulders and rotating forelimbs also help tree-dwelling pri-mates move from branch to branch They also allow humans todo the backstroke as shown in Figure 16

Primates are divided into two major groups The first groupthe strepsirhines (STREP suh rines) includes lemurs and tar-siers like those shown in Figure 17 The second group hap-lorhines (HAP luh rines) includes monkeys apes and humans

SECTION 3 The Evolution of Primates 171

Hominids About 4 million to 6 million years ago humanlikeprimates appeared that were different from the other primatesThese ancestors called hominids ate both meat and plants andwalked upright on two legs Hominids shared some characteris-tics with gorillas orangutans and chimpanzees but a largerbrain separated them from the apes

African Origins In the early 1920s a fossil skull was discov-ered in a quarry in South Africa The skull had a small space forthe brain but it had a humanlike jaw and teeth The fossilnamed Australopithecus was one of the oldest hominids discov-ered An almost-complete skeleton of Australopithecus wasfound in northern Africa in 1974 This hominid fossil shown inFigure 18 was called Lucy and had a small brain but is thoughtto have walked upright This fossil indicates that modernhominids might have evolved from similar ancestors

Figure 17 Tarsiers and lemurs areactive at night Tarsiers are commonlyfound in the rain forests of SoutheastAsia Lemurs live on Madagascar andother nearby islandsList the traits that distinguish theseanimals as primates

Figure 18 The fossil remains of Lucy are esti-mated to be 29 million to 34 million years old

Early Humans In the 1960s in the region ofAfrica shown in Figure 19 a hominid fossilwhich was more like present-day humans thanAustralopithecus was discovered The hominidwas named Homo habilis meaning ldquohandy manrdquobecause simple stone tools were found near himHomo habilis is estimated to be 15 million to 2million years old Based upon many fossil com-parisons scientists have suggested that Homohabilis gave rise to another species Homo erectusabout 16 million years ago This hominid had alarger brain than Homo habilis Homo erectustraveled from Africa to Southeast Asia Chinaand possibly Europe Homo habilis and Homoerectus are thought to be ancestors of humansbecause they had larger brains and more human-like features than Australopithecus

Why was Homo habilis giventhat name

Humans The fossil record indicates that Homo sapiens evolved about

400000 years ago By about 125000 years ago two early humangroups Neanderthals (nee AN dur tawlz) and Cro-Magnonhumans as shown in Figure 20 probably lived at the same timein parts of Africa and Europe

Neanderthals Short heavy bodies with thick bones smallchins and heavy browridges were physical characteristics ofNeanderthals Family groups lived in caves and used well-madestone tools to hunt large animals Neanderthals disappearedfrom the fossil record about 30000 years ago They probably arenot direct ancestors of modern humans but represent a sidebranch of human evolution

7 Write a story in your Science Journal about what lifemight have been like when both Neanderthals andCro-Magnon humans were alive

Cro-Magnon Humans Cro-Magnon fossils have been foundin Europe Asia and Australia and date from 10000 to about40000 years in age Standing about 16 m to 17 m tall the phys-ical appearance of Cro-Magnon people was almost the same asthat of modern humans They lived in caves made stone carv-ings and buried their dead As shown in Figure 21 the oldestrecorded art has been found on the walls of caves in Francewhere Cro-Magnon humans first painted bison horses andpeople carrying spears Cro-Magnon humans are thought to bedirect ancestors of early humans Homo sapiens which meansldquowise humanrdquo Evidence indicates that modern humans Homosapiens sapiens evolved from Homo sapiens

Figure 21 Paintings on cavewalls have led scientists to hypoth-esize that Cro-Magnon humanshad a well-developed culture

The first cases of AIDS or acquiredimmune deficiency syndrome in humanswere reported in the early 1980s AIDS is

caused by the human immunodeficiency virusor HIV

A major problem in AIDS research is therapid evolution of HIV When HIV multipliesinside a host cell new versions of the virus areproduced as well as identical copies of the virusthat invaded the cell New versions of the virussoon can outnumber the original version Atreatment that works against todayrsquos HIV mightnot work against tomorrowrsquos version

These rapid changes in HIV also mean thatdifferent strains of the virus exist in differentplaces around the world Treatments developedin the United States work only for people whocontracted the virus in the United States Thisleaves people in some parts of the world withouteffective treatments So researchers such asgeneticist Flossie Wong-Staal at the University ofCalifornia in San Diego must look for new waysto fight the evolving virus

Working BackwardsFlossie Wong-Staal is taking a new approach

First her team identifies the parts of a human cellthat HIV depends on and the parts of the humancell that HIV needs but the human cell doesnrsquotneed Then the team looks for a way to removemdashor inactivatemdashthose unneeded parts This tech-nique limits the virusrsquos ability to multiply
